Dear all,
I hope you will join us for the June LINCC Tech Talk session that will take place on Thursday, June 11, at 10am Pacific/1pm Eastern on Zoom (https://ls.st/lincc-talks). We will hear about EzTaoX by Weixiang Yu.
EzTaoX: Scalable and Flexible Multiband Modeling of AGN Light Curves in the Rubin Era
Active galactic nuclei (AGNs) exhibit stochastic variability correlated across a wide range of wavelengths on timescales ranging from days to years. Modeling and understanding AGN variability are critical for probing accretion flows in AGNs, studying supermassive black hole growth, and identifying AGNs in large photometric surveys. The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will monitor tens of millions of AGNs over a 10-year baseline, with an average cadence of three days across six bands. However, existing tools for AGN light-curve modeling are not well suited to the scale, cadence, and multiband nature of Rubin data. In this talk, I will present EzTaoX, a community software package for scalable and flexible Gaussian process (GP) modeling of multiband AGN light curves. I will highlight the technical advances of EzTaoX relative to existing tools and demonstrate several key science applications. Finally, I will discuss recent updates to EzTaoX enabled through the LINCC Frameworks Incubator Program.
LINCC Tech Talks are held on the second Thursday of every month. Events are also advertised at our web page and also provided in calendar form; and the #lincc-tech-talks LSST-DA Slack channel is always available for discussions before, during, and after the talks.
